The flavor is something deep, something that doesn't have a huge impact, but it does give you a slightly mysterious feeling and finally you understand it, and it is really, really tasty."

That is how Yashuhito Teshima describes the unique, white strawberries he is cultivating in the south of Japan. Mysterious, indeed

In Japan, some types of fruit are considered a luxury item. The fruit is delivered in ornate packaging and offered to friends and loved ones as gifts. They are so highly prized that some are sold for the price of gold.

That's the case for strawberries in Japan, and especially white strawberries. While Japan is home to several varieties of berries, the "white jewel" is the rarest and most prized. Yasuhito Teshima is the only person growing them in the entire country.

The strawberries are such a delicacy, they are sometimes sold one-by-one in individual packaging for about 10 dollars a piece. Quite the expensive treat.

In Japan, there's a specialty fruit craze sweeping the nation, from square watermelons to grapes the size of Ping-Pong balls. Still, the crown jewel of the luxury fruit basket is the white strawberry, bred to be a whole lot bigger and a whole lot sweeter than its classic red counterpart. We took a tour of Yasuhito Teshima's farm in Karatsu, Japan, to find out why so many people are spending a pretty penny for a taste of these famous white berries.
